To all whom it may concern:

Be it known that 1, WILLIAM W, ALLEN,

a citizen of the United States, residing at lVashington, in the District of Columbia, have invented certain new and useful Improvements in Demountable Rims; and I do hereby declare the followin to be a full, clear, and eXact description'of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i I

' This invention relates to vehicle rims and more particularly to demountable rims for pneumatic tires for motor vehicles, and the primary obj ect'of theinvention is to provide an improved rim formed of separate detachable sections, which will allow the tire casing to be easily removed from and placed on the rim.

Another object of the invention is to provide an improved means for holding the separate sections of the rim in locked position,

so as to absolutely prevent the displacement of the tire casing andhold the rim together when the same is removed from the felly.

A further object of the invention is to pro vide an improved demountable rim for mo tor vehicles formed in a pair of separate detachab'le sections, which are so formed in relation to each other, that the same when united will form astrong and rigid structure. i I

A still further object of the invention is to provide an improved demountable rim for motor vehicles, which is durable and efficient in use and one that is simple and easy to manufacture, and one that can be placed upon the market at ajreasonable price.

With these andopher objects in view, the invention consists in the novel construction, arrangement of 'parts' as will be hereinafter more specifically described, 1 claimed and illustratedjin the accompanyingdrawing,

forming a part thereof, in which 2' Figure 1 is a front elevation 9f the improved rim in osition on a whole wheel.

Fig. 2 is a'si e elevation of the improved rim showing the two sections separated.

Fig. 3 is a transverse section through the rim and fell showing the sections of the I rim inlocke position.

Fig. 4 is a transverse section through the rim removed from the felly showing the .same prior to being locked, and

Fig. 5 is a fragmentary interior View showing the lock.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 1 generally indicates the improved vehicle rim, which is adapted to be removably attached to the felly 2 of a wheel 3 in' the ordinary or any preferred manner. The improved rim 1 includes two separate sections 4 and 5 which have formed on their opposed side edges tire engaging flanges 6. Each of the annular rim sections 4.- and 5 respectively is provided with an 113- 'win-dly directed slot 7 formed in their inner meeting edges. These slots are in alinement 7a with each other and form means to hold the tire valve.. The rim sections 4 and 5 are so formed as to overlap each other and the outer section 4 is internally cut away from a point adjacent the tire engaging flange to 78 the opposite edge defining theannular internal shoulder 9. The inner section 5 has its external surface graduallytaperedfrom a point adjacent the tire engaging flange 6 to. its-opposite end as at 10 to conform to the 86 cut away portion 8 formed in the other rim section. The tapered portion forms an an? nnlar shoulder 11' adjacent tihe clencher rim and these shoulders 9 and 11 engage the-inner edges of the rim section and limit the 83 inward movement thereof;

The rim sections 4 and 5 are provided with a locking means 12, which holds the rim sections in operative position. The locking means 12 includes a lever 13 which is hingedly connected at its inner end to the internal surface of the rim section 4. A suitable bracket 14 is riveted or otherwise secured to the internal surface of the rim e and has spaced cars 15 which receives the an inner end of the lever 13 and a suitable pivot pin .13 extends through the ears and levers, and holds the same pivotally connected to the rim. The lever 13 is formed in two separate," sections, which are pivotally connected with each other as at 17,. Each of the lever sections are provided with a notched portion 18 adjacent to the hinge 17 and the notches formed in the outer lever section are adapted to receive a linlc, 1S) havin its ends nim is firmly secured in PlZLCQ and al-j, desire to eznphasi the as at 20 to tie internal surface oi the i section 5. The outer r'l aee ol' the is provided with spaeeu transversely ing pockets it, which forms 1U ii commodating the locking device In operation of the improved locking; means the rim sections 4 and 5 are brought "to 'ethe and the link 19 is vositioued in the a: i l

notched portion 18 of the outer lever section and the same is then swung on, the pivot 11' toward the opposite lever section and at tle same time toe lever is forced uyuvardly and when the outer lever section if\' in engagement with the inner lever section the link displacement of the rim sections is prevented.

In 1 i I I have found that the form oi my invention illustrated in the accompanying drawings and eferrerl to in the above description as the preferred on ments, is the most effioient and pr: yet realizing the conditions concurrent the adoption of my device will neee rious minor changes in details of CODSt1lC- hon; oroportion and arrangement of parts U l sorted; to rvh n required, without 'i any oi the advantages of my inm as set forth. What e. i in comoi demountahle tire rim including a A r of annular telescoping inte ting sections, means engaging said sec tions to hold the same in engagement with each other and including a loop pivotally secured to one on, a two part lever pivotally scoured to the opposite section, the 3 aria of said lever being hingeclly secured to each other and having a notch formed on each sid of the hinge, o; e pa t of said lever he adapted to overlie and engage the )art, the i hes being adapted to mine with each other to form it closed coni- I the not hes being miapteri to 11k, as and for the PHIPOSB eigiiature
